HVAC cost FAQ
- How much does HVAC repair or replacement cost?
- Most AC repairs run $200–$900 and furnace repairs $180–$850. A full system replacement typically costs $9,000–$18,000 depending on size and efficiency. Use the calculator above for a personalized estimate.
- How is the estimate calculated?
- The calculator combines the service you pick, your system type and size, home square footage and urgency. Ranges reflect typical market rates; your final quote comes from the HVAC company you contact.
- Is it worth repairing an older AC unit?
- A common rule: if the repair costs more than a third of a new system and the unit is over 12 years old, replacement usually pays off through lower energy bills and fewer breakdowns.
